So for this last week or so (when i really noticed it) my chin Andy has been acting so strange! I think i've narrowed it down to anger but not sure what from, as nothing conflict or negative has happened in between him and i

he also gets 'angry' at my bf Angry= *hissing/spitting and digging at the bars at us and he nipped me once on the arm the other day*
I know there has been packing/moving of my roommate and now i've started packing (but all the packing is done outside my room which the door stays shut so he has his 'peace and quiet' to sleep during the day with the air conditioning running to keep him at his ideal temp.) but this behavior started before all this moving stuff...it has gotten worse but STILL dont know the direct cause...anyone had a chin get angry over something??
I know he really likes his 'treats' and he would sometimes dig at the bars to get one and if it was time for him to have one, i'd give it to him...but now i open the cage and hand the treat to him, he eats it, then goes back up on the shelf and digs and acts angry. so it's not helping...

what did i do to make him so mad??
I even tried sitting down and calmly talking to him

and he sits up on his shelf and acts all normal but then if i move or even sometimes if i dont he makes mean noises towards me !!! but sometimes if i'm just sitting there looking at him trying to figure him out he'll talk to me/make noises like he's trying to tell me somehting or chew my butt! lol...but not sure why/what he wants!
So then i tried to give him lots of 'quiet time' to calm down or what not and he's still being a turd-bird!!
any ideas to calm this guy down?? advice?? questions? (i could have missed something up there ^ or not explained something well enough)
I considered vet action thinking he could be sick but his poos are all normal, he's eating and drinking normal too! and he is super energetic and such...just overly energetic towards trying to 'get at us' thru the bars?!?!?
thanks ahead of time!!
